Abstract: FIELD: personal use articles. 
     SUBSTANCE: multilayer insole consists of upper woven layer facing foot, lower woven layer adjacent to inner side of shoes and middle layer between them, which is manufactured with number of middle layers, made by plain weave from flax threads each, consisting of horizontal and vertical layers, not more than 4. Besides vertical middle layer is connected to lower horizontal layer by weaving of common woof threads of lower horizontal layer and vertical middle layer with warp threads of lower horizontal layer and vertical middle layer, and with n-th horizontal middle layer as a result of weaving of common woof threads of n-th horizontal middle layer and vertical middle layer with warp threads of n-th horizontal middle layer and vertical middle layer. With upper horizontal layer - as a result of weaving of common woof threads of upper horizontal layer and vertical middle layer with warp threads of upper horizontal layer and vertical middle layer, so that upper layer facing foot in heel part has horizontal surface formed by 48 woof threads, 100 warp threads of upper layer and 100 warp threads of middle vertical layer. Curvilinear contour of part is formed by three rectangular ledges at inner side and three rectangular ledges at field side with t number of woof threads along height of vertical middle layer, where t is selected from 2 to 14; and from warp threads for each ledge in areas of bevels for inner and field sides of heel parts, where c=6, via b woof vertical layers. Where b=4 and a warp threads between inner and field sides of heel part, where a=76; and d woof vertical layers of field side of heel, waist and toe parts, where d=176. In toe part it has horizontal surface formed by 104 woof threads, 140 warp threads of upper layer and 140 warp threads of middle vertical layer. Curvilinear contour of part is formed by five rectangular ledges at inner side with s number of woof threads along height of vertical middle layer, where s is selected from 2 to 9; and with c, f, c, f warp threads for each ledge in area of bevel for field side of toe part, where c=6, f=12, via e, g, e, b of woof vertical layers, where e=8, g=12, b=4, and three rectangular ledges from warp threads for each ledge in area of bevel for inner side of toe part, where c=6, via b woof vertical layers, where b=4; and h warp threads between field and inner sides of toe part, where h-90, and i woof vertical layers of inner side of toe part and waist parts, where i=84 with s, r number of woof threads along height of vertical middle layer, where s is selected from 2 to 9, and r is selected from 2 to 10. In waist part there is a horizontal; surface made by 96 woof threads, 140 warp threads of upper layer and 140 warp threads of middle vertical layer, curvilinear contour of which is formed by three rectangular grooves at inner side with o, p, q, r number of woof threads along height of vertical middle layer, where o is selected from 2 to 13; p is selected from 2 to 12; q is selected from 2 to 11; r is selected from 2 to 10; and with f warp threads for each groove in area of bevel for inner side of waist part, where f=12 via j, k woof vertical layers, where j=16, k=24; and 1 woof vertical layers of inner side in waist and toe parts, where l=68, besides number of woof threads along height of vertical layer is not more than 14. 
     EFFECT: improved manufacturability of process as a result of simultaneous running of layers and their connection by method of single-shed figured dobby weaving in textile machinery with simultaneous increase of insole service life and adjustable elasticity of insole, which takes into account features of human foot structure in process of wearing.
